I think overall this is a very good product in this price. I am sensitive to allergies and I didn't get any problems while using this product. It is certified organic, and I could see, taste & feel that the quality is really very good.
A few cons though. Taste wise, it has a very neutral flavour, not much of Vanilla. Not easy to mix in water or milk. Derived from sprouted brown rice, this is probably not a complete protein (Nutribiotic website itself tells that Lysine and Histidine are not in sufficient amounts to qualify it as a complete protein). So you should include protein from other food sources/supplements (especially if you are into building muscle).
